Description

Technical Field

[0001] The present invention relates to the technical field related to refractory materials, and in particular to a casting molding equipment for non-carbon steel ladle bricks and a brick-making method for the equipment. Background Art

[0002] A steel ladle is a container for holding molten steel, made of steel, lined with non-carbon steel ladle bricks, and the molten steel flows out from the bottom opening for casting. The steel ladle is one of the important equipment in steelmaking production. The working conditions of the steel ladle are relatively harsh. The inner lining bears the static pressure of the high-temperature molten steel and the severe impact during tapping, and undergoes rapid mechanical erosion, chemical erosion, and rapid cooling and heating of the temperature. This causes the inner lining of the steel ladle to be damaged by melting, and in severe cases, the steel ladle leaks, posing a hidden danger to safety production. Non-carbon steel ladle bricks are used as inner lining bricks for metallurgical containers, especially for containers such as steel ladles.

[0003] Non-carbon steel ladle bricks are relatively common heat-insulating materials in high-temperature firing furnaces. Most of the common non-carbon steel ladle bricks on the market are regular cuboid or cube structures. In some scenarios, the steel ladle needs to have a certain arc or rounded corner and other curved surface shapes, and non-carbon steel ladle bricks with different lengths or arcs and different curvatures will be used. However, the existing brick molds cannot achieve the production of non-carbon steel ladle bricks with multiple shapes using a single set of molds. Summary of the Invention

[0004] The present invention aims to overcome the deficiency that the shape of the existing non-carbon steel ladle brick mold is single and unchangeable, and provides a casting molding equipment for non-carbon steel ladle bricks that can produce non-carbon steel ladle bricks with different shapes according to requirements and a brick-making method for the equipment.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A casting molding equipment for non-carbon steel ladle bricks includes a brick mold, a pouring pipe, and a power rotating mechanism. The port part of the pouring pipe extends into the brick mold. The brick mold is provided with an upper mold frame and a bottom template connected to the lower bottom surface of the upper mold frame. The upper mold frame and the bottom template form a box body with an upper opening. The upper mold frame is provided with a fixing plate and a sliding plate slidably connected to the fixing plate. The sliding plate is connected to the power rotating mechanism, and a vibration device is connected to the outer side surface of the fixing plate.

[0007] The pouring pipe is externally connected to a batching device and extends into the brick mold, and the prepared mixture is poured into the brick mold. The brick mold includes an upper mold frame and a bottom template, and the upper mold frame and the bottom template form a box body with an open upper part. The upper mold frame includes a fixed plate and a sliding plate. The sliding plate is slidably connected to the fixed plate, and the sliding plate is hinged to a power rotating mechanism. The power rotating mechanism can drive the sliding plate to move. The sliding plate slides along the fixed plate to adjust the size of the brick, and non-carbon steel ladle bricks of different sizes can be obtained. The power rotating mechanism can drive the sliding plate to rotate, change the shape of the fixed plate, and cause the formed box body to change, so as to obtain an arc-shaped non-carbon steel ladle brick. Different rotation angles of the power rotating mechanism can obtain non-carbon steel ladle bricks with different radian. A vibration device is connected to the outer side surface of the fixed plate. The vibration device impacts the fixed plate, and the mixture injected into the brick mold is vibrated to make the gaps between the mixture components smaller and more compact. After sintering, non-carbon steel ladle bricks with better strength can be obtained.

[0008] Preferably, the fixed plate is a plate member made of an elastic material. A chute is arranged on the top surface of the fixed plate, and a fixing block is arranged in the middle of the bottom surface. The fixing block is fixedly connected to the bottom template. The fixed plate is made of an elastic material and realizes the changes in the shape and size of the brick mold through elastic deformation. The chute arranged on the top surface can enable the sliding plate to slide along the chute to change the length size of the brick mold and obtain non-carbon steel ladle bricks with different lengths. The fixing block arranged on the bottom surface can ensure that the middle part of the bottom surface of the fixed plate is fixed on the bottom template, ensuring that both ends of the fixed plate can displace and the middle part remains stationary, realizing the change in the form of the brick mold, and thus obtaining non-carbon steel ladle bricks with different forms.

[0009] Preferably, sliders are hinged to both ends of the sliding plate. The sliders are cylinders. The sliders are embedded in the chute and are slidably connected to the chute. A limiting block is arranged on the top surface of the slider, and the lower bottom surface of the limiting block contacts the upper surface of the fixed plate. The sliding plate can adjust the length change of the inner cavity of the brick mold through the sliding of the sliders embedded in the chute, and non-carbon steel ladle bricks with different lengths can be obtained. The sliders are hinged to the sliding plate and can adjust the angle between the sliding plate and the fixed plate when the fixed plate undergoes elastic deformation to meet the adaptation to the change in the form of the brick mold.

[0010] Preferably, the power rotating mechanism includes a rotating motor, a driving rod, and a driven rod. The driving rod and the driven rod are strip-shaped rods. A connecting block is provided at the end of the driving rod. An electric motor mounting hole is provided on the upper surface of the connecting block, a guiding block is provided on the lower surface, and a driving gear is provided on the end face.

The rotating motor drives the driving rod to swing. The driving rod and the driven rod are stacked and connected. The guiding block is embedded in the rotating groove. The driving gear provided on the driving rod meshes with the driven gear provided on the driven rod. The swinging of the driving rod can drive the driven rod to swing, thereby driving the sliding plate to swing, and further driving the sliding plate to swing, causing the brick mold to change in shape, obtaining non-carbon steel ladle bricks with different shapes, that is, different swinging angles result in non-carbon steel ladle bricks with different arcs.

[0011] Preferably, guiding grooves are respectively provided on the bottom surfaces of the driving rod and the driven rod. A telescopic mechanism is provided in the guiding groove. The telescopic mechanism is fixedly connected with a connecting rod, and the connecting rod is hinged to the outer side surface of the sliding plate. The telescopic mechanism provided in the guiding groove can be an optional cylinder or other telescopic mechanisms with telescopic functions. The telescopic mechanism fixedly connected with the connecting rod drives the sliding plate to slide, adjusting the length change of the inner cavity of the brick mold, obtaining non-carbon steel ladle bricks with different lengths.

[0012] Preferably, the bottom template is provided with a through hole and a mounting hole penetrating the bottom template. The fixing block is embedded in the mounting hole and fixedly connected. The through hole is located outside the outer surface of the fixing plate and is aligned with the mounting hole. The mounting hole provides the installation position of the fixing block to ensure the fixed installation of the fixing plate; the through hole provides the installation position of the vibration device to ensure the feasibility of the vibration function.

[0013] Preferably, the bottom template is provided with a stop block, and the stop block is located between the through hole and the fixing plate. The setting of the stop block can prevent the mixture in the brick mold from seeping out too much and causing pollution.

[0014] Preferably, the vibration device includes a vibration arm and a vibration motor. The vibration arm is U-shaped. The vertical arm of the vibration arm passes through the through hole, and the horizontal arm is fixedly connected with the vibration motor. The vibration motor drives the vibration arm to vibrate. The U-shaped vibration arm can simultaneously impact the two outer side surfaces of the fixing plate, improving the impact vibration efficiency, making the mixture in the brick mold more compact, and the fired non-carbon steel ladle bricks more solid.

[0015] Preferably, a vibration block is provided at the top of the inner side of the vibration arm. The vibration block is hemispherical and contacts the outer wall of the fixed plate. The spherical vibration block can make the vibration effect stronger, improve the impact vibration efficiency, make the mixture more compact in the brick mold, and make the fired non-carbon steel ladle brick more solid.

[0016] A brick-making method for a casting-molded non-carbon steel ladle brick manufacturing device is as follows:

[0017] 1) Material mixing: Mix materials such as aggregate and binder to obtain a mixture.

[0018] 2) Pouring into a blank: Adjust the shape of the brick mold according to production requirements. The telescopic mechanism drives the connecting rod to slide, and the connecting rod drives the sliding plate to slide along the chute to adjust the length of the inner cavity of the brick mold. The rotating motor drives the active rod to swing, driving the driven rod to swing. The active rod and the driven rod drive the sliding plate to swing to adjust the arc of the brick mold. Pour the mixture into the brick mold through the pouring pipe, and the vibration device vibrates to compact the mixture in the brick mold into a blank. Pour the mixture into the brick mold through the pouring pipe, and the vibration device impacts the fixed plate to vibrate at the same frequency, and the mixture in the brick mold is compacted to complete the production of the brick blank.

[0019] 3) Baking into a brick: Bake the brick blank to obtain a non-carbon steel ladle brick.

[0020] The beneficial effects of the present invention are: Non-carbon steel ladle bricks of different shapes can be produced according to requirements; the fixed plate is made of an elastic material, and the shape of the brick mold can be changed through elastic deformation; the slider slides along the chute to adjust the length of the inner cavity of the brick mold; the power rotating mechanism drives the slider to swing to adjust the arc size of the brick mold.
